I try to switch from HTTP to HTTPS:
func handler(w http.ResponseWriter, req *http.Request) {
w.Header().Set("Content-Type", "text/plain")
w.Write([]byte("This is an example server.
"))
}
func main() {
http.HandleFunc("/", handler)
log.Printf("About to listen on 8080. Go to https://127.0.0.1:8080/")
err := http.ListenAndServeTLS(":8080", "cert.pem", "key.pem", nil)
if err != nil {
log.Fatal(err)
}
}
And I am getting the following error:
crypto/tls: failed to parse key PEM data
My application is running in HTTP mode now and I want it to run in HTTPS mode.
Can anyone suggest how to make it work in HTTPS?
